Splash-backed Poison Frog
Adelphobates galactonotus
The Splash-backed Poison Frog (Adelphobates galactonotus) is a bold, relatively large dendrobatid frog. It is named for the striking, solid patch of color (white, red, or yellow) that covers its back, resembling splashed paint.

Species description
Geographical Origin and Habitat: Distributed across the primary rainforests of the southern Amazon basin in Brazil, specifically within the Tapajós and Pará river basins. This species is strictly terrestrial, inhabiting the damp, shaded leaf litter of the forest floor, seeking shelter under fallen leaves, rotting logs, and coconut shells near slow-flowing streams.
Taxonomy and Genetics: A member of the Dendrobatidae family, widely known as the splash-backed poison frog. It is popular in the hobby due to its striking natural color morphs (red, orange, yellow, white, and spotted variations). The dorsal coloration features a solid, vibrant patch of color that contrasts sharply with the dark black or brown base of the rest of the body.
Behavior and Habits: Terrestrial and relatively bold compared to other poison frogs. They are slow, deliberate walkers but can make short hops if startled. They are active during the day and frequently explore open areas. Males produce a soft, buzzing call to attract females during the breeding season. Parents carry tadpoles on their backs to water sources.
Morphology: A robust frog, reaching up to 4 cm in length. Females are generally larger, rounder, and heavier when carrying eggs. Males are slightly smaller and more slender, with longer fingers and a vocal sac used during courtship.
Care, breeding and tankmates
Terrarium Setup: Best kept in a spacious, vertically short terrarium (e.g. 60x45x45 cm) for a small group. Use a thick layer of drainage substrate (such as clay balls) covered by leaf litter (oak or ketapang leaves) to provide hiding spots. Include pieces of cork bark and mosses, avoiding tall climbing branches as they are primarily terrestrial.
Lighting and Heating: Requires a warm tropical climate, with daytime temperatures between 24 and 26°C. Temperatures should not exceed 28°C, as overheating is fatal. A slight drop to 21°C at night is beneficial. Provide low-intensity UVB lighting (typically 5%) to prevent metabolic bone disease.
Humidity and Hydration: Maintain high humidity levels between 80% and 90% through regular misting with purified water. Proper ventilation is critical to prevent stagnant air and bacterial infections such as red leg syndrome. A shallow water bowl or damp moss area should always be available.
Feeding and Supplementation: Strictly insectivorous, feeding on small live prey such as fruit flies (Drosophila hydei and melanogaster), springtails, and micro-crickets. Food must be dusted with calcium and vitamin D3 supplements three times a week to prevent nutritional deficiencies.
Compatibility: A peaceful species that can be housed in small groups or harems (e.g. two males and four females in a suitable setup). They do not display the intense territorial aggression seen in some other dendrobatids. Avoid mixing with other species or genera to prevent cross-contamination.
Health and Common Diseases: Highly sensitive to skin toxins and chemicals. Handling should be avoided, as oils and soap residues on human hands can cause fatal irritation or stress. Common health issues include bacterial infections from poor sanitation and dehydration from inadequate misting.

The catalog's scalar value is 4.05 cm. The AmphiBIO v1 source reports a maximum adult measurement of 4.05 cm for this species, recorded as snout–vent length (SVL). These figures are not interchangeable: the first is the profile's editorial reference, whereas the second is a published maximum under a specific measurement convention; differences among sources can reflect sex, population, life stage and measuring method.
